I looked for Verne Tyler on the 1910 census and found him living with Frank and Clara Cole and listed as stepson to head of household. So the Clara Tyler Cole in the cemetery is almost certainly the mother of Roscoe and Verne and probably Mabel as well. Plus...she has had seven children with six living, so there are three others to account for. I haven't been able to find her in 1900, however. She and Frank had been married six years in 1910, and if they were married in Wayne County we'll have their marriage license on microfilm.
